I would say very unlikely. The R1 Antrouter might be thought of an an entry level Miner, however we have only seen one small batch of those so even it's future is uncertain. They also have their hands pretty full with S7 shipments and revisions at the moment.

Last I heard CrazyGuy had both R1's and U3's in stock if your wanting them. Make sure to select custom firmware when buying, the automatic fixing of zombies on UE3 is awesome.
That firmware changed my life for the easier, that is for sure.
